The invention discloses a casing deformation
wireless monitoring system in well cementation, fracturing and production processes, which comprises an underground casing deformation
wireless monitor, a
transmission channel, a
signal relay device and a ground receiving
system, and is characterized in that the underground casing deformation
wireless monitor and a
casing string enter a well together, the casing deformation condition is detected while the casing is centralized, and the
signal relay device is connected with the ground receiving
system; a casing transformation
data signal is modulated, excited and transmitted outwards, the
signal relay device amplifies and re-transmits the casing transformation
data signal, the ground receiving
system receives and demodulates the casing transformation
data signal from the signal relay device, and the multi-point detection condition of underground casing deformation is obtained through
computer processing. And information such as the deformation position, the deformation degree and the number of casing deformation points of the underground casing can be accurately obtained in real time. According to the invention, real-time monitoring and risk prediction can be carried out on casing deformation conditions in operation construction stages of casing lifting and lowering,
cement paste well cementation, perforation, fracturing, production and the like, and positive practical significance is provided for guaranteeing long-acting development of oil and gas resources.
